One leg's RENDERED contribution at a point, joint machinery and the
widthScale dimming included — the mirror of the fragment shader (default
sharpness knob, fade omitted; see the block comment above), CLIPPED to the
stencil the vertex stage builds for it. The clip is not decoration: a
fragment outside the stencil is never rasterized, so a reach shortfall
chops the profile to zero instead of dimming it, and a model that
evaluated the profile over the whole plane would be structurally blind to
the entire #1488 defect class.
That load-bearing part is the JOINT-END reach, and only it — the arm the
negative control exercises. The other two clips here, the perpendicular /
free-far-end box and the hairpin fallback's rMax, mirror the vertex stage
for completeness and are provably non-binding while the shipped reaches
hold (profile > 0 already implies a point inside both). Deleting either
leaves the suite green, by construction rather than by oversight.
